Class ConcurrentMapCacheManager

java.lang.Object
  extended by org.springframework.cache.concurrent.ConcurrentMapCacheManager
All Implemented Interfaces:
CacheManager

public class ConcurrentMapCacheManager
extends java.lang.Object
implements CacheManager

CacheManager implementation that lazily builds ConcurrentMapCache instances for each getCache(java.lang.String) request. Also supports a 'static' mode where the set of cache names is pre-defined through setCacheNames(java.util.Collection), with no dynamic creation of further cache regions at runtime.

Since:
3.1
